Correct, however I am so not aware of what mix is in there currently.

I've been running straight water (see first post), I drained it out yesterday, was pretty murky with coolant in there as well.
After draining it out yesterday, I tried to follow some instructions stating: "Put 1 1/2 Gallon of Antifreeze after draining, and top off with water."

I got 3/4 of the first thing of coolant before it became a bad idea, mostly because I'm dumb and did it with a warm engine. It filled to the top and didn't continue emptying into the system, so I drained it out again, ran water until it came out clear.
I then premixed a jug of coolant to a good 50/50, if anything 45(w)/55(c) and added it until the message went away.

That's when I took it out for a spin, floored it for a couple seconds, and then got massive overheating.

I checked the purge line this morning, nothing was coming out. Coolant level is low.

Coolant/water ratio is irrelevant at this point. It will not cause the engine to overheat or use coolant. I am more concerned with your "suuuuuuuuper puffy and hard to squeeze" hose. Get that purge line to flow. Rod out the hollow bolt and blow through the rest of the line. If it's clogged, clear it. Then if you still overheat, do the block test.

I took a wire hanger to it this morning. In as far and as much as I could go, nothin, even after started the engine with the tube off to see if it would flow. I put coolant in recently, felt the hose but it was probably the engine vibration I felt. I will check the hollow bolt again soon.

The hollowbolt that I poked through the first time, or the other end of the hose?

When I 'rodded' (which I am assuming means to push a wire hanger through) the hollowbolt the first time, daaaaays back. I got bubbling / falling into a stream.

When I did it this morning, nothing came out of the hollowbolt, and nothing came out of the hose (except initially some black liquid residue came out, not a lot). No bubbling, no stream, nothin. Even when I ran the car.

Why is this so hard? Hollow bolt is rodded out. The line is clogged. Clear it with compressed air or a long piece of 12 gauge wire. Put it back together and let the engine purge itself. This is not rocket science. It should not take 10 pages to accomplish this and be able to move on.
